Request consent from the baby's other parent. Although state procedures differ, all child name changes require consent or notice to the other parent, giving her a chance to block the change. Obtain her consent, if possible, to make the process easier.
Visit your state legislature's official website. States typically have the laws, or directions on where to find the laws –– like a public library –– available online. Name change laws are typically found under the civil remedies and procedures sections of state laws. You want the legal requirements to change the name of a minor in your state.
Visit the official website of your state's judicial system. Check each court type to see what cases are handled. Locate the court that processes name changes. Name change courts typically include county circuit and district courts.
Contact the court clerk's office. Ask if you're permitted to file a name change for a baby, without an attorney, if the forms are available at the court and the filing fee amount. Some courts don't allow you to file a name change without an attorney.
Get the name change forms. Go to the court if the forms are available there or to the place the court clerk directed you to. Forms vary by area, but you commonly need a petition and a consent form from the other parent. If your state laws require a public posting of your baby's name change, you'll also need a notice form. In that case, ask the court where in the building the notice change must be posted.
Complete the petition. Formats vary by area, but you usually need the baby's name as shown on her birth certificate, where and when she was born, her proposed name, her current address and your name, address and relationship to her. Sign and date the form.
Fill out the parental consent form. You typically need the baby's information from the petition and the name and address of the other parent. Ask the other parent to sign and date the consent in front of a notary for notarization.
Bring the original petition, consent form and the fee payment back to court. File the papers. The clerk will tell you if a hearing is needed in your county or if the court will simply mail the signed name change order for your baby back to you.
